플라스틱 버퍼 튜브 추출 튜브 전문 제조

Our plastic extraction tubes with integrated filter caps are essential components in rapid antigen testing kits. The built-in filter ensures clean, particle-free sample extract for accurate lateral flow immunoassay results.

These tubes are designed for the extraction and filtration of nasal swab, throat swab, and saliva samples. The extraction buffer is added to the tube, the swab is inserted and mixed, and the filtered extract is dispensed directly onto the test cassette through the nozzle cap.

We manufacture extraction tubes in multiple configurations — including round-bottom, conical-bottom, with or without pre-filled buffer — to match the specific requirements of different rapid test kit designs. Our automated assembly line handles tube forming, filter insertion, nozzle cap assembly, and buffer filling in a single production flow.
